Definitions
- the present invention relates to an alarm device comprising a housing adapted to be mounted adjacent to a ceiling, said housing including detector means and alarm means responsive to said detector means.
- the invention further relates to a housing for an alarm device.
- alarm devices such as smoke, fire, gas and burglary alarms comprising various smoke detectors, gas detectors and infra-red light detector in combination with different alarm means such as alarm sounder means and alarm lighting means.
- smoke alarms are very often mounted as a box, which is screwed into the ceiling of a room, where there is a risk of a fire to start. Although such smoke alarms can be decorative, they are still foreign objects for a living room or an office. Similarly, burglary alarms are mounted as visible foreign objects, and it may be undesirable that such alarms are visible to an intruder.
- GB 2 221 074 A discloses a smoke detector device which, in use, forms part of a ceiling light fitting, comprising a housing adapted to be mounted adjacent to a ceiling and having an aperture in a lower-most surface thereof to allow the passage of an electrical flex (cord) therethrough, said housing enclosing smoke detector means and alarm sounder means responsive to said detector means.
- the housing can be of dimensions comparable to conventional ceiling rose light fittings, and this prior art smoke detector will not be visible as a smoke detector by a person entering a room, where the smoke alarm is built into a ceiling rose light fitting hiding the connection between the cord of a swinging lamp and an AC power outlet in the ceiling surface.
- the present invention provides an alarm device comprising a housing adapted to be mounted adjacent to a ceiling, said housing including detector means and alarm means responsive to said detector means.
- the housing is adapted to replace existing ceiling rose fittings, but is - in contrast to GB 2 221 074 A - adapted to be carried by a cord extending from a ceiling so that fixation directly to the ceiling is avoided. Consequently, the alarm device according to the present invention is adapted to be maintained and fixated relative to a cord extending from the ceiling without having the alarm device connected to or fixated to the ceiling surface or to an electrical installation box or power outlet located at the ceiling.
- a lighting smoke alarm which smoke alarm is composed of two parts, a first part to be fixated relative to the ceiling and a second part constituting a hollow or dome-shaped part to be arrested relative to the first part by means of a snap fitting or a threaded connection.
- the second part has a bottom hole, through which the cord extends and which hole is provided with a conventional unloading or relief fitting.
- the housing is generally configured as an egg having a top and bottom wire inlet and outlet and is provided with cord guiding elements serving to allow the housing to be suspended in the cord at a position below the ceiling.
- the housing comprises a hollow body having an upper circumferential edge and a lower circumferential edge, said hollow body having an inner surface facing the inner space defined within said hollow body, said lower circumferential edge defining an aperture to allow passage of a cord into said inner space, and a plurality of elastically bendable, elongate members, each having a length exceeding the width of said aperture and each having a proximal end and a distal end, the proximal ends of said elastically bendable, elongate members being located at said inner surface of said hollow body above said aperture, said plurality of elastically bendable, elongate members being orientated pointing to said aperture and said distal ends of said plurality of elastically bendable, elongate members defining a free opening therebetween being smaller than said aperture, said distal ends of said plurality of elastically bendable, elongate members being adapted to engage the surface of a cord extending from a ceiling, and to carry said alarm device through said engagement, when said alarm device is mounted
- the upper circumferential edge is intended to face the ceiling and will keep the housing in place, when carried by the cord of a swinging lamp, when the alarm device is mounted adjacent to a ceiling.
- the elastically bendable, elongate members being adapted to engage the surface of a cord extending from a ceiling may carry the alarm device by means of frictional resistance, provided said resistance is sufficient to carry the weight of the housing enclosing detector means and alarm means.
- detector means and alarm means of very low weight can be manufactured and will not add substantially to the weight of a housing manufactured in ABS plastic.
- the hollow body is a symmetrical body having a central axis of symmetry and each of said elastically bendable, elongate members defining an angle less than 90° such as an angle less than 80°, preferably less than 60°, preferable an acute angle, relative to said axis of symmetry.
- the elastically bendable, elongate members have a length constituting at least two times, preferably 2-5 times such as 2-3 times the aperture through which a cord passes into the inner space of the housing.
- the free opening between the elongate members should be somewhat smaller than the cross section of the cord of a swinging lamp, and the smaller said free opening is relative to the cord the higher the frictional resistance will be. Also the longer the elastically bendable, elongate members are relative to the distance from the proximal ends of the elongate members to the surface of the cord, the more the elongate members will bend and thus provide additional friction resistance.
- a constructor of ordinary skill in the art will be able to determine the optimum dimensions of the elastically bendable, elongate members to provide a frictional resistance which is sufficient to carry the housing enclosing detector means and alarm means, at the same time making it easy to push the housing upwards on a cord to face a ceiling with the upper circumferential edge.
- detector means and alarm means within the housing is preferably made symmetrical to the central axis of the housing so as to stabilize the alarm device adjacent to a ceiling.
- the pre-stressing of the elasticaily bendable, elongate members, when bent will push the upper circumferential edge of the housing towards the ceiling and thus keep it in place and prevent it from tilting.
- the plurality of the elasticaily bendable, elongate members may be integrally connected to a separate annular body to be received within the inner space of hollow body and preferably snapfitted into engagement with the inner surface.
- the annular body and the hollow body from different plastic materials.
- the annular body could be manufactured from PE or PP and the hollow body could be manufactured from ABS.
- the hollow body comprises two or more hollow body parts, which are interconnected by means of co-operating latching means for generating said hollow body.
- the hollow body is composed of two hollow body parts being releasably interconnected by means of co-operating latching means extending along respective side edges of each of said two hollow body parts.
- the two hollow body parts can be two identical shell parts having the co-operating latching means extending along a side edge extending in a direction parallel to the central axis of symmetry of the assembled hollow body.
- each of the two hollow body parts may comprise at least one, preferably two, elastically bendable, elongate members and said aperture to allow passage of a cord will be formed by interconnecting said two hollow body parts, whereby the alarm device is mounted on an existing cord extending from a ceiling by moving the two hollow body parts enclosing said cord laterally towards each other to engage said latching means.
- one of the hollow body parts may enclose both the detector means and the alarm means as well as a battery for power supply.
- the alarm device can then be mounted around the cord of a swinging lamp by pressing the two body parts laterally against each other at eye level to engage the latching means whereby the elastically bendable, elongate members defining a free opening therebetween will be pressed with their distant ends against the cord, and when the assembled housing is pushed upwards against the ceiling the elongate members will bend downwards and provide a pre-stressing or distortion of the housing against the ceiling.
- the co-operating latching means releasably interconnected, it is possible to dismount the alarm device by pressing one of the two hollow body parts apart from the other hollow body part.
- a battery power supply can be replaced and the detector means and/or alarm means can be cleaned.
- the housing as such can be cleaned.
- An alarm device requiring a power supply can obtain such power supply from a DC9V battery, from a rechargeable battery or from 230/115V AC through a resistor.
- the alarm device When the alarm device is a smoke detector device, it can be mounted adjacent to the ceiling of a room, where there is a risk of a fire to start. Through the main-power supply of a building the smoke detector device in one room can be connected to alarm devices in other rooms so that alarm means can be activated in other rooms than the one where a fire has started.
- the smoke detector means will normally be either ionic alarms or optical alarms, both of which are activated by smoke rising from a fire.
- the alarm device of the present invention is a smoke alarm device care should therefore be taken that smoke can enter into the housing and reach the ionic or optical detector means.
- the gap between the cord and the circumferential edge of the cord aperture may be sufficient to allow a sufficient passage of smoke, but in order to improve the draught one or more further apertures may be provided in the housing between the upper circumferential edge and the lower circumferential edge. Also cuts of other openings may be provided in the upper circumferential edge of the housing to facilitate a smoke activating the detector means.
- the alarm device of the present invention can replace a ceiling rose fitting and thus act as a ceiling rose fitting, even if it is not being used as an alarm device. Therefore, in a separate aspect the invention also provides a housing for an alarm device, the housing being defined as described in the foregoing and further comprising means for mounting detector means and alarm means responsive to said detector means within the inner space defined within the hollow body.
- the means for mounting detector means and alarm means can easily be constructed by an ordinary person skilled in the art, who will know how to make sure that the alarm device can be activated in the surroundings where it is placed.

- the outer surface of the hollow body part 10 is disclosed, and in Fig. 2, the interior of the hollow body part 10 is disclosed.
- the body part 10 is a curved shell divided into two sections 12 and 14 by an ornamental line 16 which line serves the purpose of dividing the outer basically conical surface of the assembled housing into a total of four identical surface parts which surface parts such as the surface parts 12 and 14 are separated from the adjacent surface part by an edge of the body part 10 and the separation line 16.
- the body part 10 defines a semicircular top edge 18 and a bottom semicircular edge 20.
- the top edge 18 has a dimension allowing the assembled housing composed of two identical body parts 10 to enclose a cable and/or connector, etc. within the inner space defined within the interior of the assembled housing when assembled from two identical body parts 10.
- the diameter of the lower semicircular edge 20 allows an electric cord or electric cable to be introduced through the aperture defined by the two body parts when assembled into a composite housing having a bottom aperture defined by the two semicircular edges 20 of the two body parts.
- the bottom aperture defined by the two semicircular edges 20 of the two body parts 10, from which the composite housing is assembled is substantially larger than the outer diameter of the electric cable or cord for allowing the cable or cord to be easily introduced into the bottom aperture of the assembly housing, and for allowing a gas to pass into the interior of the housing.
- a further aperture 20a above the lower circumferential edge 20 facilitates passage of a gas, such as smoke from a fire.
- the one edge interconnecting the top edge 18 and the bottom edge 20 is designated the reference numeral 22 and as illustrated in Fig. 2, the edge 22 is provided with two inner arresting flanges 24 serving to fit into and rest in a pair of inner surface recesses 26 provided at the opposite edge 28 of the body part 10.
- the opposite edge 28 is further provided with two additional flanges 30, serving the purpose of fitting into and resting within corresponding recesses at the inner surface at the edge 22.
- a number of cut-outs 32 are shown provided at the upper edge 18 of the body part 10, which cut-outs serve the purpose of facilitating passage of a gas, such as smoke from a fire through the housing.
- Elements 62 for fixating a box containing alarm and detector means are fixed to the interior of body parts 10.
- a particular feature of the housing assembled from two body parts 10 relates to the safe and reliable fixation of the housing composed of two body parts relative to the electric cable or cord, the distant end of which is connected to en electrical lamp or similar appliance and the proximal end of which is hidden within the inner chamber defined within the housing as the proximal end is connected to the permanent installation of the room.
- the safe and reliable fixation of the housing enclosing detector and alarm means is established by means of a plurality of elongated and flexible arresting arms two of which are shown in Fig. 2 and designated the reference numeral 34.
- the arms 34 are mounted on posts 36 for positioning the arms in an acute angle relative to the cable or cord which' is guided through the bottom aperture defined by the two semicircular bottom edges 20 of the two body parts 10.
- the outer ends 38 of the arms 34 are sharp as the arms have their outer inner faces inclined relative to the longitudinal axis of the arms 34.
- a particular feature of the arms 34 relate to the fact that the arms are orientated extending from the posts 36 towards the bottom edge 20 for allowing the assembled housing as is illustrated in Fig.
- the barb-like arms 34 have, as is illustrated in Fig. 2, a fairly large major dimension or length as compared to the diameter of the cable or cord to which the barb functioning arms are to arrest and the fairly large length serves the purpose of positioning the arms in an acute angle relative to the cable or cord and at the same time provide the relevant flexibility of the arms for obtaining the intentional function like arresting barbs.
- the first and presently preferred embodiment of the housing for use as or according to the present invention described above with reference to Figs. 1 , 2, 3a and 3b and being implemented as a two part structure may be modified in numerous ways, e.g. in accordance with the fittings described in inventor's non-published EP-A 0438025.1 and inventor's previously published international patent application WO 96/21123 to which reference is made, and which specifications are to be considered part of the present specification.
- the outer shell of the housing is constituted by an integral unitary structure as is illustrated in Fig. 5 in which the shell is designated the reference numeral 10'.
- components or elements identical to components or elements, respectively, described above are designated the same reference numerals, whereas components or elements serving the same purpose as components or elements, respectively, previously described, however, geometrically differing from the previously described components or elements, respectively, are designated the same reference numerals, however added a marking identifying the geometrical difference.
- the flexible barb-like arresting arms 34 characteristic of the present invention are integrally included in the body part 10
- the barb-like arresting arms of the embodiment shown in Fig. 5 are included in a separate component 50 which is snapfitted into the interior of the shell 10'.
- the component 50 is produced in a separate moulding process and includes a ring-shaped body 52 from which a total of four arms 34' extend downwards serving the same purpose as the arm 34 described above with reference to Figs. 3a and 3b.
- ring-shaped body 50 is shown in greater details illustrating the angular orientation of the arms 34' and further the snapfitting of the ring-shaped body 50 to the inner surface of the fitting 10' behind a circumferential rim 48 at the inner surface of the shell 10'.
- the structure described above with reference to Figs. 1 , 2, 3a and 3b may be modified by the introduction of a separate arresting ring similar to the ring 50, and similarly, the integral arresting arms 34 described above with reference to the first embodiment shown in Figs. 1 and 2 may be integrated into the unitary structure embodiment 10' shown in Figs. 4 and 5.
- the integration of the arms 34 into the embodiment shown in Fig. 4 may cause severe problems in the moulding process and necessitate the use of a highly advanced and elaborate injection moulding tube.
- a separate arresting ring such as the ring 50 shown in Fig. 4 may be advantageous from the point of view of simplicity of manufacturing the fitting.
- the use of a separate arresting component rather than integral arresting arms allows the outer shell body 10' to be made from one material such as a fairly stiff and solid material, whereas the arresting ring may be made from a softer and more flexible material ensuring and fulfilling the requirements as to flexibility of the arresting arms.
- Relevant materials for the housing and components such as the arresting ring 50 of the fitting are plastics materials such as polyethylene (PE), polypropylene (PP), polyoxymethylene (POM) and acrylonitrile butadiene styrene (ABS).
